Look at how excited Duke is!
Now let me tell you the story of why Duke is so excited.
Duke is only allowed tennis balls twice a year, on Christmas and his birthday. You see, Duke can't control himself around tennis balls. It's like he forgets that he mother was a shih-tzu because those pitbull jaws take over and that tennis ball is lucky to stay whole for three minutes. Now I will spend the next week fishing tennis ball pieces out of Landon's mouth no matter how many times I vacuum.
And that is all that remains of that poor red tennis ball.
